i asked about installing FC3 on a CD-less laptop on the fedora list just a while ago, and i was given the following link:
http://www-2.cs.cmu.edu/~colohan/docs/fedora_upgrade.html
which looks like it will do just what i want. (the laptop is, in fact, running FC2 at the moment, so i appear to be good to go.)
my only question is, that web page talks strictly about doing an upgrade. i would like to totally repartition the drive and use LVM, which is not the way it's set up now.
the question is, once i use grub to get the initial kernel and initrd, and i select an NFS install, and i repartition and start the install, is there no further use for all of the isolinux/ stuff i copied onto the hard drive on the laptop?
that is, am i safe in assuming that the install process is done with all of the isolinux/ stuff so that the repartitioning won't hurt anything? that *seems* to be the case, but i'd rather know for sure. thanks.

When using any media with just the isolinux boot stuff, it is safe to remove the media as soon as the installer loads.
With media that has a local installer, this is not the case. You cannot remove Disk one until prompted, when installing from Disk1, even if you do a kickstart. My understanding, from observation, is that if there is a local installer, the disk will remain mounted, even if the installer is not used.

ok, that seems to jive with the test i just ran, where i copied the isolinux stuff into /boot, booted from that and, as part of the install, reformatted /boot (thereby blasting all the isolinux stuff). no problem, the laptop is installing as we speak. must remember this trick.

When installing from disc 1, a CD install will automatically be used. Once you're installing from CD, disc 1 will be mounted. To avoid doing this, you can use 'linux askmethod' at the boot: prompt. It is then safe to remove the installation disc once the loader screen comes up.

I think it currently tries to find a local installer image even if you're using a network install method....

First of all, it's much easier to just use the vmlinuz and initrd from images/pxeboot. These are the same files as the ones on the boot.iso image, but you don't have to go to the trouble of loopback mounting to get to them.
When grub loads the kernel and initrd from the hard disk, it places them in memory. The files are only needed on the disk at boot time. After the installation process is finished you can totally repartition/format the disk without any trouble. You just won't be able to boot into the installer again if you nuke the filesystem or bootloader setup...
But hopefully you're replacing everything with a bootloader for the freshly installed system anyway.

Matt

Robert,
We use a program written internally called "kickme" which places the PXE initrd and vmlinuz into /boot and sets up GRUB to automatically boot from them. We use this to re-kickstart machines as needed with newer images, etc.
If you're interested, check it out here: https://sourceforge.net/project/showfiles.php?group_id=34678
Grab kickme-0.2-1.noarch.rpm.
